Embodiment Construction

[0024]The following detailed description illustrates embodiments of the disclosure by way of example and not by way of limitation. It is contemplated that the disclosure has general application to analytical and methodical embodiments of heat management using radial tubular heat exchangers configured to operate within a duct, pipe, fluid flow path, or other fluid conduit.

[0025]Embodiments of the disclosure provide a lightweight and conformal heat exchanger solution integrated to the bypass duct assembly. Other embodiments provide for a heat exchanger mounted within any flow path, such as, but not limited to exhaust streams, ducts, piping, vessels, or tanks. A mounting plate arrangement provides a pocket cavity to distribute fluid fed from an integral plenum into the individual tubular serpentine arrangements for heat exchange. A bolted and sealed plate arrangement allows modular assembly of the heat exchanger units and modular manufacturing of the brazed tube joints. A serpentine co...

Abstract

A method and a system for a heat exchanger assembly are provided. The heat exchanger assembly includes one or more arcuate heat exchanger segments each including an inlet header configured to extend circumferentially about a circumference of an inner surface of a fluid flow duct, and an outlet header configured to extend circumferentially about the fluid flow duct. The heat exchanger assembly also includes a first serpentine heat exchanger tube extending between the inlet header and the outlet header and including a series of flow path segments having a gradually changing direction defined by a bend radius of the tube such that a direction of flow through the serpentine heat exchanger tube reverses between the inlet and the outlet headers and a second serpentine heat exchanger tube extending between the inlet header and the outlet header, the second serpentine heat exchanger tube co-planar with the first serpentine heat exchanger tube.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This non-provisional application claims the benefit of priority under 35 U.S.C. §119(e) to U.S. Provisional Patent Application No. 62 / 019,171, entitled “METHOD AND SYSTEM FOR RADIAL TUBULAR HEAT EXCHANGERS”, filed Jun. 30, 2014, which is herein incorporated in its entirety by reference.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH & DEVELOPMENT[0002]The U.S. Government has certain rights in this application as provided for by the terms of Contract No. FA8650-09-D-2922.BACKGROUND[0003]This description relates to heat exchangers, and, more particularly, to a method and system for a radially-oriented circumferential heat exchanger.[0004]Gas turbine engines typically include an inlet, a fan, low and high pressure compressors, a combustor, and at least one turbine. The compressors compress air which is channeled to the combustor where it is mixed with fuel. The mixture is then ignited for generating hot combustion gases. The combustion gase...
